- If the object is at equilibrium, then the net force acting upon the object should be 0 Newton. Thus, if all the forces are added together as vectors, then the resultant force (the vector sum) should be 0 Newton. (Recall that the net force is "the vector sum of all the forces" or the resultant of adding all the individual forces head-to-tail.)

This interactive skill-building activity challenges students to use concepts of vector components and equilibrium in order to balance the forces acting upon an object. One or more forces are given and students must add a north-south force and an east-west force to balance the given force (s).
Jan 30, 2023 · The activity of a substance (abbreviated as a) describes the effective concentration of that substance in the reaction mixture. Activity takes into account the non-ideality of the reaction mixture, including solvent-solvent, solvent-solute, and solute-solute interactions.

If an object is at rest and is in a state of equilibrium, then we would say that the object is at "static equilibrium." "Static" means stationary or at rest. A common physics lab is to hang an object by two or more strings and to measure the forces that are exerted at angles upon the object to support its weight. The state of the object is analyzed...
The above analysis of the forces acting upon an object in equilibrium is commonly used to analyze situations involving objects at static equilibrium. The most common application involves the analysis of the forces acting upon a sign that is at rest. For example, consider the picture at the right that hangs on a wall. The picture is in a state of eq...
There is an important principle that emanates from some of thetrigonometric calculations performed above. The principle is that as the angle with the horizontal increases, the amount of tensional force required to hold the sign at equilibrium decreases. To illustrate this, consider a 10-Newton picture held by three different wire orientations as sh...
Sep 12, 2022 · The first equilibrium condition for the static equilibrium of a rigid body expresses translational equilibrium: ∑ k →Fk = →0. The first equilibrium condition, Equation 12.2.2, is the equilibrium condition for forces, which we encountered when studying applications of Newton’s laws.

Demonstration and discussion: The washing line (10 minutes) Student experiment: Forces in different directions (15 minutes)
Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.
A Force is not just as how strong it is, but also, what direction it acts in. So, forces are best described as vectors, with magnitude and direction. Using vector theory, forces can be resolved into a horizontal and a vertical components. Then learners can use these components to see what will happen to objects when these forces are applied.
